- Abstract
Aims The twisting motion of the heart has an important role in the function of the left ventricle. Speckle tracking echocardiography is able to quantify left ventricular ( LV) rotation and twist. So far this new technique has not been used in congenital heart disease patients. The aim of our study was to investigate the feasibility and the intra- and inter-observer reproducibility of LV rotation parameters in adult patients with congenital heart disease. Methods and Results The study population consisted of 66 consecutive patients seen in the outpatient clinic (67% male, mean age 31 ± 7.7 years, NYHA class 1 ± 0.3) with a variety of congenital heart disease. First, feasibility was assessed in all patients. Intra- and inter-observer reproducibility was assessed for the patients in which speckle tracking echocardiography was feasible. Adequate image quality, for performing speckle echocardiography, was found in 80% of patients. The bias for the intra-observer reproducibility of the LV twist was 0.0°, with 95% limits of agreement of −2.5° and 2.5° and for interobserver reproducibility the bias was 0.0°, with 95% limits of agreement of −3.0° and 3.0°. Intra- and inter-observer measurements showed a strong correlation (0.86 and 0.79, respectively). Also a good repeatability was seen. The mean time to complete full analysis per subject for the first and second measurement was 9 and 5 minutes, respectively. Conclusion Speckle tracking echocardiography is feasible in 80% of adult patients with congenital heart disease and shows excellent intra- and inter-observer reproducibility.
